Mechanisms linking lung cancer to PM2.5 dust.
Mechanisms linking lung cancer to PM2.5 dust.
Particulate matter smaller than 2.5 micrometers (PM2.5) can enter the body through the respiratory system and directly affect the lungs. The mechanisms by which PM2.5 causes lung cancer include:
1. DNA damage and cell mutation
PM2.5 contains toxins such as heavy metals (such as cadmium and arsenic) and carcinogens (such as polycyclic aromatic hydrocarbons, or PAHs), which can trigger DNA mutations and cause lung cells to become cancerous.
2. Oxidative Stress
PM2.5 particles stimulate the production of free radicals (ROS), causing oxidative stress. which can damage cells and important proteins As a result, normal cells can change into cancer cells.
3. Chronic inflammation of the lungs
When the body is exposed to PM2.5, immune cells secrete cytokines and various inflammatory substances. Causes chronic inflammation in the lungs which is an important factor that promotes the birth and growth of cancer cells
4. Changes in the lung microbiome (Lung Microbiome Dysbiosis)
PM2.5 dust disrupts the balance of microorganisms in the lungs. This results in a decrease in beneficial microorganisms. and causes inflammation and an increased risk of cancer.

Benefits of resveratrol and reducing the effects of PM2.5 dust
Resveratrol is an antioxidant found in red grapes. and some plants Which has properties to help reduce the impact of PM2.5 on the body as follows:
1. Reduce oxidative stress (Oxidative Stress)
Resveratrol reduces the production of free radicals and strengthens cellular defenses against PM2.5 damage.
2. Anti-inflammatory (Anti-inflammatory Effects)
This substance reduces the secretion of inflammatory substances (such as IL-6, TNF-α) stimulated by PM2.5, reducing the risk of chronic inflammation in the lungs.
3. Protect lung cells from DNA damage
Resveratrol can stimulate proteins that help repair DNA and reduce the chance of mutations that can lead to lung cancer.
4. Helps balance the lung microbiome.
Research indicates that resveratrol helps balance the microorganisms in the lungs. This reduces inflammation and cell damage.
5. Improves the efficiency of the immune system
Resveratrol can stimulate immune cells to be more effective. Makes the body better able to eliminate toxins and abnormal cells caused by PM2.5.

Summary
PM2.5 dust is involved in increasing the risk of lung cancer through DNA damage mechanisms, stimulating inflammation. and oxidative stress Resveratrol can help reduce the effects of PM2.5 by acting as an antioxidant, reducing inflammation, and protecting cells from mutations. Consuming resveratrol from supplements is one way to reduce the risk of PM2.5-related diseases, including lung cancer.
